SIG-NAL.

Application filed .Tune 8,

To aZZ whom it may concern.' .Y

Be it known thatr, JAY Cook, a citizen of the United States, residing at Coldwater,

in the county of Branch and Statie of Michigan, have invented anew and useful Signal, of which the following is a specification.

This invention aims to provide a simple means whereby a signal maybe displayed at a railroad crossing, when a train proaching the crossing. 1t 1s within the provlnceof the disclosure to improve generally andv to enhance ther utility of devices ofthat type to which the invention appertains.

, )Vith the above and other objects in view,

which will appear as the description pro Ceeds, the invention resides in the combination and arrangement of partsv and in the details of construction hereinafterjdescribed and claimed it being understood that, within the scope of what is claimed, changes in the precise embodiment of the inventionshown V:can bev made without departing from the of the rails 2 and 3 are united b spirit'ofthe invention. In the accompanying drawings :-l

Figure 1 shows in top plan,`a device constructed in accordance with` the invention;

Figure 2 lis a side elevation wherein parts are removed; Figure 3 Vis a section on the line 3 3 of Figure 1; Figure 4 1s va Ysection on the line 4-4 of Figure 2;` Figure 5 is a section o n the line 5-5 of Figure 1.

In the drawings, there is shown a railroad track comprising, at one side, a rail 1, and comprising, atrits opposite side, rails 2 and 3, the numeral 4 denoting a highway crossing. The purpose of the invention is to provide a means for displaying a signal at the `-on certain of the .ties 10, is provided with depending projections 11 (Figure 5) engaging the inner edges of the said ties, the projections being spaced apart. The upper surfaces of the projections 11 slant downwardly and inwardly to form a seat or recess 12.

Disposed below one of the ties 10 is a'casing 14 having an inwardly extended horizontal guide 15 (Figure 2). A plunger 16 is vbottom of the casing 1 A bell crank lever 21 is locatedin thecas-H,

1923. serial No. 644,194.,

mounted for reciprocation .in the guide 15, in the upper portion of the casing 14, and 1n the inner fish plate7, between the projections 11,.as shown best in Figure 5. The

plunger 16`issupplied'at its upper endr with'` be convexed as indicated 'at '18,' the head 1 7 being located close to the spaced ends of the*`v rails 2 and 3, asshown inFigUre 1. The; head 17 is equipped. with a lateral lug 19 mounted to slide in the recess 5 whichexists a head 17, the upper surface of which may., V

between the ends of therails` 2 and j3. Ai'

compression spring 2O is interposed between the lower end of the plunger 16 and the ing 14 and is fulcrumed at 22 on bearings 23 carried by the casing'14. The bell crank lever 21 comprises a short lateral arm, re-4 ceived in a slot 24 formed in the plunger 16,

the bell 'crank lever comprising a longer upstanding arm which is pivoted at, 25400 an operating member or rod. 26, slidably re- ,i

ceived in a tubular shield 27, one end of the shield beingconnected to the casing 14 andv the other end of the shieldbeing connected to the enlarged base 28 of an upright tubular standard29, the upperportion'otl thebase j. l

28v being provided withaaphinged lid 30 giver ing access to the, working parts within the` base 28. VConnections31 are interposed in the tubular shield 27 and extend upwardly above the surfaceof' the ground, screwplugs,I Y

32 or Vother closures being mounted in thej connections 31.l When the plugs 32 arev re moved, a lubricant maybe inserted into the tubularshield 27. It will be understood that the tubular shield 27 and the operatingrmem! ber or rod 26 may b e of. anydesired length, so that the casing 14 maybe llocated at considerable distance Vfrom the standard 29,

thereby to afford an adequate period of time.`

between the actuation of the signalmechai,

nism, 'hereinafter described, and the arrival of the train at the highway crossing 4.

The operating member or rod 26 extends within the base 28 of the standard 29 and is. pivoted at 33 to an armf 34 on a horizontal.

shaft 35 (Figure 3) journaled vin bearings 36 located on opposite side walls of the base v 28. The-'shaft 35 is supplied with an arm v-v y37, disposed at an ,angle to the arm34, Athe arm 37 being pivoted at 39 to a pitman 38 .which extends upwardly through the stands ard 29.

At its upperend, the standard 29 is pro` vided with` a transverse head 40 which is open'at the bottom, the head being provided at one end with an enlargement 41. A lever 42 is located in the head 40 and is ulcrumed intermediate its ends, as at 43,011 the standard 29.V One end of the lever 42 projects` Y beyond the head 40 as shownin Figure 2 and carries a counter-weight 44, adjust-ably held invplace by a set screw 45 oithe like.

The upper end of the pitman 8S is pivoted. ,tov 'the lever 42, as indicated at 46. 'The lever 42 carriesk a Aplate 47 housed ywithin "'wl'ien that vend of the 'lever which carries the plate 47 swings upwardly, the Vspring` asclearly shown in Figure 2. A'spring Varm 48 is connected at one end tothe 'headv K the plunger, a'shai'ft mounted to rock in the 4G-and is adapted to engagethe lever 42,

arm 48 being a cushioning spring, the func tion `of which will be understoodl clearly l when Figure Y2 oil-theV drawings is examined.

*In practical operation', when the'wheel ofr alocomotive engine or other piece or rolling vstock moves along the rails`2 and 3,v

the iiange ot the wheelinay engage the ,con-

Vvexed surface 18 of thehead 17 of the "plunger '16, or the body portion of the wheel may engage the lug- 19 on the head 17.` In any event, the plunger 16 will be forced' downwardly, the spring 2O being compressed. f When the plunger 16 movesVV downwardly, the bell crank 21 will be tilted on its fulcrum 22 and motion 'will be imv parted to the operating niember'orrod 26, the shaft 35 being rotated by way of the ,garni 34, and the arm 37 imparting movev ment to the pitman '38,' the pitman moving downwardly'i'n the standard 29 andA tilting the lever 42 on its fulcrum' 43, .the plate 47 being exposed with respect to the enlarge- Yment` 41 et' the arm 37 on the'st-andard '29, notice thusfbeing given tothe driversl Alter the wheels of the train have passedV oil" the head 17 of the plunger 16, theplunger 16 moves upwardly, responsive to the action of the spring 20, the parts being restored to the positions of Figure 2 by the action Ot the spring 20, assisted by the action of theadjustable weight 44 on the lever '42, onearm of the bell crank lever 21 also assisting in restoring the'par-ts to the positions shown in Figure 2. The head preferably is bolted tothe plunger, and is so con-A structed, as shown in Figure 17, that it will aid kin freeing the ice from the rail, should icel accumulate onlthe rail. It will be` ob y vi-ous that the structurer shownv in this ap- Vture in the presence of two t incassa way the train is moving on the track, this detail being a mere duplication, well understood by those skilled in the art andrequiring no specific delineation.
